Title: Reflectometre optique a domaine temporel (otdr) et reseau de supervision optique integres
Inventor: LEMUS-TEJADA ENOS AVID
IPC: H04B10/08
Filed: 2001-11-20
Abstract: L'invention concerne un mécanisme OTDR/OSC intégré destiné à surveiller un système de transport optique sans perturber l'utilisation normale de celui-ci. L'invention combine deux composantes essentielles de réseaux dans un mécanisme intégré. Ces composantes sont la fonction de canal de supervision optique (OSC) de rigueur dans le cadre de n'importe quel réseau DWDM, et des caractéristiques internes, en service du moteur OTDR. Une paire de longeurs d'onde de commande suffit à mettre en oeuvre les deux fonctionnalités OSC et OTDR. Ainsi, une fonction de commande répartie, des procédure OTDR et la surveillance de fibre sont mise en oeuvre, lorsque l'acquisition de traces à partir d'un emplacement quelconque du réseau devient possible. En assemblant ces deux composantes essentielles de réseau, l'invention permet de mieux gérer le réseau et d'en réduire les coûts de maintenance. Ceci découle du fait que l'invention permet d'utiliser et de commander le moteur OTDR à distance, et que la combinaison avec la fonction OSC permet une mise en oeuvre rapide des procédures OTDR sur des canaux de fonctionnement à l'intérieur de chaque fibre de câble.

Title: Crane system with a continuous conveying system for part-load transport
Inventor: JONKE HANS
IPC: B65G67/60
Filed: 1990-02-01
Abstract: ABSTRACT         One or a plurality of circular conveyors are arranged at the transition points between vertical and horizontal conveyor sections in a continually operating conveyor system for moving items of freight, in particular sacks, cases, bundles, or the like.  The truncated conical surface of a circular conveyor that carries the items of freight subtends an angle of other than 90° with the axis of rotation of the vertical conveyor and is in constant movement independent of the direction of rotation or the orientation of the vertical conveyor.  The safe, non-damaging transfer of the items of freight between the vertical and the horizontal conveyor sections is ensured by the position of the inner edge of the surface at the level of the transition point (guide wheels) of the supporting platforms of the vertical conveyor.

Title: Circular saw rotator
Inventor: MUIR DAVID L
IPC: B24D99/00
Filed: 1990-02-13
Abstract: BACKGROUND OF THE INVENTION An addition for the manually operated Circular Saw Sharpeners SUMMARY OF THE INVENTION This invention is directed to the rotation of a circular saw blade to its position for sharpening, using the slight movement of the foot. It has a major safety factor in that it is hand and finger free until completely sharpened. The saw depth guide eases straining of the eyes. It erases a time element of marking and is a positive depth finder. The brake is a com-bination of two safety factors: one it locks a blade in position until sawtooth is sharpened, the other movement is to rotate the blade to the left or right as necessary - mainly used for rotating blades with a gullet, such as a combination, eliminating the use of the hands and fingers.

Title: Bucket lift bar
Inventor: CROWE GROVER W
IPC: B66F11/04
Filed: 1990-03-19
Abstract: (ss. 21, 31, 34, & 142) ABSTRACT   The combination "Digger Derrick Bucket Truck" is a very versatile piece of equipment used by electric and communication utilities and contractors. The type of truck referred to here has the Derrick mounted on the right rear corner next to the curb and is carried with the boom tip out over the front of the truck body over the cab. These booms have a winch and a cable mounted on the boom tip which is used to lift things like poles or electrical equipment. The bucket of these trucks is mounted on the tip of the boom also usually on a fibreglass extension that can slide in or out. This is the most beneficial place for it as far as reaching out and up is concerned. While these buckets can be left on or taken off, a lot of the time it is carried right on the boom. When the bucket is put in the transporting position on the boom it must be swung up to a horizontal position so it is up over the cab of the truck and also over the windshield level so the driver can see. These buckets are very heavy and must be lifted to and from the transport position by hand. This invention is a tool that enables a lineman to raise and lower this bucket using the winch on the boom tip to lift the weight.

Abstract: This invention pertains to movable storage systems wherein a series of storage units having shelves or bins are supported on wheeled carriages to provide for moving the units on tracks to create an access aisle between any two of the units and to establish the others in close side-by-side relationship to minimize the amount of floor space required for the units. There i.s a reversible electric motor mounted on each of the :storage units so the units can be driven in either direction along the tracks. In particular, the invention resides in a new limit switch assembly which is capable of governing the time at which acceleration anal deceleration of the units occurs as they are moved in series to close a presently open aisle and to thereby create the space for opening a presently closed aisle between units.      Details of the electrical controllers which are mounted on the individual movable storage units and a more extensive description of all of the structural and operating features of a mobile storage system are described in U.S. Patent No. 4,759,592.

Abstract: METHOD AND MEANS FOR DETERMINING EXHAUST BACKPRESSURE      IN A CRANKCASE SCAVENGED TWO-STROKE ENGINE     Abstract of the Disclosure A method and means are described for determining the average backpressure at a cylinder exhaust port in a crankcase scavenged two-cycle engine. The exhaust backpressure is determined by averaging the pressure of air within a crankcase chamber associated with the cylinder, during a portion of the engine operating cycle when the cylinder inlet and exhaust ports are simultaneously open.  The overlap interval in port openings creates a channel for airflow between the crankcase chamber and the cylinder exhaust port, and except for an initial portion of the interval associated with the pressure equalization between the cylinder and its crankcase chamber, the crankcase pressure substantially equals the backpressure appearing at the cylinder exhaust port.  In the preferred embodiment of the invention, a pressure sensor is disposed within the crankcase chamber to sample air pressure at specified engine rotational positions during the overlap interval.  These samples are then numerically averaged to obtain the average exhaust backpressure, which is used for compensating the amount of air inducted per cylinder per engine cycle to determined the amount of air per cylinder trapped and available for combustion within the engine. The control of the engine is thereby automatically corrected to account for changes in the engine exhaust system, the altitude of engine operation, and local barometric pressure.

Abstract: An apparatus for the controlled ventilation of a room has a control mechanism, which includes a quantity control and measurement means, and is incorporated in a ventilation duct portion.  The control mechanism includes a tubular, hollow body in the form of a flow body which has two pressure measuring chambers arranged successively in flow direction.  The chambers are provided with rows of openings which produce a connection to flow-through cross-sections of the control mechanism which have different airflow speeds. The airflow is measured by means of a differential pressure detector, which is connected to the pressure measuring chambers by means of two short passages. The apparatus has a low airflow loss and a low flow noise.  As a result of its favourable flow guidance, the apparatus may be positioned directly adjacent to branching points of a ventilation duct.
